Transparent Curve (For Drafting)

Hello all,

I’m looking for a workaround to creating a transparent curve… trying to replicate a nice ‘detail’ linetype in a layout.

I’ve tried SetObjectDisplayMode (only works for objects obviously)
I’ve tried locking the curve and changing locked object transparency under display settings… but only effects objects.

Does anyone have any suggestions or workarounds? I know I could use a transparent hatch in Rhino WIP 7, but I want something quick that will reflect what my linetype scale is.

Thank you in advance
